IPC: F23G5/50
Filed: 1989-01-13
Abstract: PURPOSE:To securely prevent the upward shift of combustion by changing the position of waste charging according to the quantity of waste, amount of moisture attached to it, or the temperature of the operation zone in addition to a furnace temperature control by means of an ordinary burner. CONSTITUTION:For a multi-stage incinerator 1 a set temperature is set by and indicated on a temperature setting adjustment device 17, the set temperature being the temperature at which no unburned waste remains in the incinerator ash, and the combustion quantity of a burner 15 is controlled by a combustion control valve 13 so as to keep below a set value the deviation between a detected temperature by a temperature sensor 16 installed in the combustion zone 10 and the set temperature. When the deviation (for example, 2t/H) between a detected quantity of the waste (for example, 3t/H) and a set quantity of the waste (for example, 5t/H) is above a set deviation (for example, 1t/H) range, a quantity of waste in proportion to the deviation and calculated by a waste quantity calculator 25 is charged from a first charging port F1 at the top of the furnace, and second charging ports F2 below the second stage. Similarly if the deviation is, for example, 3t/H, the position of charging the waste is changed to the second charging port F2 of the second stage, and the second charging port F2 of the fifth stage. In the same way the charging port is selected by the deviation between the detected amount of moisture attached to the waste and a set amount of moisture attached to the waste, and the waste is supplied to the incenerator.

Title: Iron-based alloy excellent in resistance to erosion by molten zinc
Inventor: WAKITA SABUROU
IPC: C22C38/56
Filed: 1980-01-25
Abstract: PURPOSE: To provide the Fe-based alloy which has an improved resistance to erosion by molten zinc in spite of a lowered Co content by adding specified amounts of C, Si, Mn, Ta (Ta+Nb), Mo and W to an Fe-Cr-Co-Ni-based alloy.  
     CONSTITUTION: The Fe-based alloy contains 0.01W3wt% of C, 0.01W2% of Si, 0.01W2% of Mn, 1W6% of Ta or Ta+Nb, 1W10% of Mo and/or W, 10W30% of Ni, 10W30% of Co and 10W25% of Cr, the balance consisting essentially of Fe and inevitable impurities. Since the alloy is excellent in erosion resistance, it exhibits excellent performance when it is used, for instance, as a material for such members as the sink roll, bath tank and the like of a galvanizing device, for casting, working machining, padding welding or metal spraying. In addition, since the amount of expensive metals such as Co used in the alloy is small, the alloy can be produced at low cost.

Abstract: PURPOSE:To improve safety by arranging the constitution in such a way that a pallet supporting member having a stopper, at the upper face, for engaging with a pallet is provided at a transfer port and the driving of the supporting device is stopped when overloading is caused at the time of the supporting member retreatment. CONSTITUTION:A supporting device 20 comprising an electric cylinder 27, levers 24a, 24b, a supporting member 21 and stoppers 29a, 29b is provided for the transfer port of a pallet 10 so that the bottom of the pallet 10 may be supported. The electric motor 27 is so constituted that it may be stopped at overloading by providing a current limit relay. By this constitution, the pallet 10 is supported or released by advancing or retreating the supporting member 21 by the expansion or contraction of the electric cylinder 27. Since the stopper 29a, 29b are hooked in grooves at the bottom of the pallet 10 which are not shown in the figure when it supports the pallet 10, the stoppers 29a, 29b contact with the groove wall and causes overload when the supporting member 21 retreats and stop the cylinder 27 preventing the pallet from falling down. In this way, the safety is improved.
